571 - What are black holes, and how are they formed?

A black hole is like a super-powerful vacuum in space that sucks up everything that gets too close, including stars, planets, and even light.

Black holes are formed when a huge star runs out of fuel and then collapses in on itself. Imagine a huge star that's like a big balloon. When it runs out of fuel, the balloon starts to shrink and shrink until it becomes so small and dense that it creates a strong gravitational pull.

This pull is so strong that nothing, not even light, can escape once it gets too close to the black hole. That's why it's called a "black" hole, because it's invisible and we can't see it.

Here's a simple example to remember:

1. A huge star runs out of fuel.
2. The star collapses in on itself.
3. The star becomes a super-dense point, creating a strong gravitational pull.
4. The strong gravity creates a black hole that sucks up everything that gets too close.

That's how black holes are formed.
